Flipping FTGL glyphs

After finally getting FTGL to work for me, I noticed that FTGLTextureFont:s render themselves upside down in my viewport. I could probably invert them by scaling my texture matrix by 1, -1, 1, but I'd rather not mess around with the GL state in that way, that much. I suppose that it would be possible to edit the FTGL itself, but before I embark on such a mission, I thought I'd ask if anyone has worked themselves around this in a more obvious way?

Considering your origin is top-left of the window, how did you properly flipped the font? I cannot do it by just scaling the y to -1 because its translating up above the screen by the font height. I have your old problem, can you give the solution?
